How to solve xml load parsing soap payload using nusoap? - php

Question

I am new in using web service nusoap. When I try to run my program I got an error like this:
XML error parsing SOAP payload on line 1: Not well-formed (invalid
token)
Here is my client.php :
<?php
require_once('lib/nusoap.php');
$data = json_decode(file_get_contents("php://input"), true);
$doc_type = $data['doc_type'];
$transaction_date = $data['transaction_date'];
$file_name = $data['file_name'];
$file_path = $data['file_path'];
//create client instance
$client = new nusoap_client('http://computer_name:2224/WebService/webservice.php?wsdl' , true);
//to check if the request method is POST or not
if($_SERVER['REQUEST_METHOD'] == 'POST'){
//check for error
$err = $client->getError();
if($err){
//Display error
echo '<h2>Constructor error </h2> <pre>' . $err . '</pre>' ;
}
//declare variables
$datas = array(
'doc_type' => $doc_type,
'transaction_date' => $transaction_date,
'file_name' => $file_name,
'file_path' => $file_path
);
//call the function InsertData and pass the parameters being instantiated
$result = $client->call('InsertData', $datas);
if($client->fault){
echo '<h2> Fault (Expect - The request contains an invalid SOAP body) </h2> <pre>';
print_r($result);
echo '</pre>' ;
}else {
$err = $client->getError();
if($err){
echo '<h2> Error </h2><pre>' . $err . '</pre>' ;
}else {
echo '<h2> Result </h2><pre>' ;
print_r($result);
echo '</pre>';
}
}
} else if ($_SERVER['REQUEST_METHOD'] != 'POST'){
echo "Method is not POST";
}
?>
webservice.php
<?php
// require the nusoap.php
require_once ('lib/nusoap.php');
//create new instance
$server = new soap_server();
//initialize WSDL support
$server->configureWSDL('Database Data Insertion', 'urn:Insert');
//character encoding
$server->soap_defencoding = 'utf-8';
// Registering different functions of your Web service
$server->register ('InsertData',
array(
'doc_type' => 'xsd:doc_type',
'transaction_date' =>'xsd:transaction_date',
'file_name' =>'xsd:file_name',
'file_path' =>'xsd:file_path'), //input values
array('return' =>'xsd:string'),
'urn:Insert', // Namespace
'urn:Insertwsdl#InsertData', //SoapAction
'rpc', //style
'literal' // can be encoded but it doesn't work with silverlight
);
// function for inserting data
function InsertData($doc_type,$transaction_date,$file_name,$file_path) {
//set initial values for connection
$db_host = 'localhost' ;
$db_username = 'root' ;
$db_password = '' ;
$db_name = 'sample' ;
//making connection
$conn = new mysqli($db_host, $db_username ,$db_password , $db_name);
//checking if connection is successful
if($conn->connect_error){
trigger_error('Database connection failed : ' .$conn->connect_error , E_USER_ERROR);
}
//inserting data in the edi_doc_type table
$sql = "INSERT INTO transaction_tbl (`transaction_date`,`edi_doc_type_id`,`file_name`,`file_path`,`creation_date`)
VALUES ('$transaction_date',( SELECT edi_doc_type_id FROM `edi_doc_type` WHERE doc_type = $doc_type ),'$file_name','$file_path',NOW()) " ;
//Checking query if it is successful
if ($conn->query($sql) === false){
trigger_error('Wrong SQL: ' . $sql . 'Error: ' . $conn->error , E_USER_ERROR);
}else {
echo "Successful ! Data is inserted in database ^__^" ;
}
}
$HTTP_RAW_POST_DATA = isset ($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA: '' ;
$server->service($HTTP_RAW_POST_DATA);
?>
Now , when I try to run this I got the above error. so what could be the possible problem? By the way, I can still insert in my database , but the problem is it returns the above error and not all the data in the script can be inserted . When I check my php error logs I have this :
PHP Fatal error: Wrong SQL: INSERT INTO transaction_tbl
(transaction_date,edi_doc_type_id,file_name,file_path,creation_date)
VALUES ('2015-05-28 22:33:00',( SELECT edi_doc_type_id FROM edi_doc_type
WHERE doc_type = 997),'87749-20150528223345027_54423526_54423945.xfa','/home/sample/test/87749-20150528223345027_54423526_54423945.xfa',NOW())
Error: Subquery returns more than 1 row
C:\xampp\htdocs\WebService\webservice.php on line 65
Any help will be appreciated. Thanks :)
